Abstract

TÉCNICAS PARA COMPARTILHAMENTO DE TEMPO DE OCUPAÇÃO DE CANAL UE-PARA-UE EM ESPECTRO NÃO LICENCIADO. Vários aspectos da presente divulgação geralmente se referem à comunicação sem fio. Em alguns aspectos, um primeiro equipamento de usuário (UE) pode determinar, dentro de um tempo de ocupação de canal compartilhado com um segundo UE, um ou mais tempos de início de partição de contenção com base, pelo menos em parte, em uma duração de escutar antes de falar e uma duração de controle de ganho automático. O primeiro UE pode transmitir uma comunicação de sidelink para o segundo UE em um tempo de início selecionado a partir de um ou mais dos um ou mais tempos de início de partição de contenção. Vários outros aspectos são providos.TECHNIQUES FOR EU-TO-EU CHANNEL OCCUPANCY TIME SHARING IN UNLICENSED SPECTRUM. Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may determine, within a shared channel occupancy time with a second UE, one or more contention partition start times based, at least in part, on a duration of listening before speaking and an automatic gain control duration. The first UE may transmit a sidelink communication to the second UE at a start time selected from one or more of the one or more contention partition start times. Various other features are provided.
